Question

A fireman leaned a 28 foot ladder against a building. If he placed the ladder 14 feet from the base of the building, what angle is formed between the ladder and the ground

Answer 1

The ladder makes an angle of 60 degree from the ground.

Explanation:

Length of the ladder, L = 28 feet

distance of ladder, d = 14 feet

Let the angle formed with the ground is A.

According to the trigonometry

`\cos A =(d)/(L)`

`\cos A =(14)/(28)`

cos A = 0.5

A = 60 degree
